A method of salt grinding of pigments wherein the material to be ground is milled with a salt, an organic conditioner, and larger particles such as balls, nails, or in a strong kneader for comminuting the pigment to the desired state of subdivision. This grinding mass is made into a smooth flowing suspension by addition of more organic conditioning agent rather than solvents, as heretofore.
Wetting dispersing additives have an influence on this stage, by modifying the surface tension at the interface they can help and accelerate the pigment wetting. » Understand Substrate Wetting Theory Here! DISPERSING: The grinding equipment (dissolvers, grinding mills, sand mills.) introduce mechanical energy in the system. This shear forces energy breaks and separates the pigment ...

If solids, especially pigments, are not broken down into smaller particle sizes and spread evenly throughout the liquid base during the paint manufacturing process, the result is a poor paint quality. This can affect everything from leveling and sagging to color and gloss quality as well as other attributes.
Grinding resins in waterborne pigment preparations for industrial use During the last years the acceptance of waterborne applications for industrial coatings has increased. These coatings should of course be as colourful as solventborne coatings. The colouration can be achieved either via grinding the pigments or with pigment preparations. In the
The present invention is directed to a polyester polycarbamate polymeric pigment dispersant to be used as a grind resin to incorporate pigment into pigment dispersions for coating compositions. The pigment dispersant is the reaction product of a first compound having a plurality of hydroxyl groups, a carboxylic acid anhydride, a second compound having at least one epoxy group, and a carbamate ...
The viscosity of a premixed dispersion is one of the main parameters to consider when selecting a particular milling equipment for grinding of pigment. Generally, high viscosity dispersions are not easy to grind using a labscale recirculating bead mill.
In the industry, the fineness of grind is generally achieved with a 2step process. First, developers and producers of paints use a dissolver to reduce the particle size of their pigments and fillers to a certain degree of fineness. Then, when needed, they additionally use a pearl mill to further separate the solid particles from each other.

What is paint and how is it made? To most people, paint is the colour on the walls of their home, the colour of their car, boat or caravan. Paint is more than just the colour though; it is a material that is applied as a liquid and dries by a variety of chemical processes to a solid.
An analytical centrifuge is an instrument which evaluates the stability of a colloidal system by accelerated gravitational settling. A LUMiSizer® dispersion analyser was used in this study to analyse the tendency to sedimentation of pigment in the optimised, waterborne pigment dispersions.

pigment dispersions with XM2311 can be formulated at a high solids. Picture 1 shows a pigment dispersion prepared according to Table 4 with a pigment to binder ratio of 1/1 using a Irgazin DPP BO red pigment and a grinding time of 16 hours on a pebble mill and let down with a PUD dispersion. The same pigment dispersion diluted
Ball milling is a grinding technique that uses media to effectively break down pigment agglomerates and aggregates to their primary particles. Using a rotor or disc impeller to create collisions of the grinding media, the impact and force created by the bead mills collisions break down the pigment agglomerates.
